Assessment of the Relationship Between ERBB4 rs13393577 Polymorphism and Breast Cancer Susceptibility in Iranian Population

Background: Studies have shown that the polymorphism of genes involved in breast cancer in combination with environmental factors has an important role in the progression of breast cancer. Objectives: In this study, the association between polymorphism of the ERBB4 gene with breast cancer was investigated. Methods: In the present study, 110 patients with breast cancer and 110 healthy individuals were selected as controls. DNA extraction was performed on patients’ samples. The tetra-ARMS-PCR method was used to study rs13393577 polymorphism. Finally, statistical analysis was performed using SPSS software using t-test. Results: The results of the study in the patients' group showed that the frequencies of TT, CT, and CC genotypes were 73, 15, and 1.8%, and allelic frequency in this group for T and C alleles were 95 and 5%, respectively. In addition, the results of the study in the control group showed that the frequencies of TT, CT, and CC genotypes were 86, 11, and 0.9%, respectively. The allelic frequencies in the control group for the T and C alleles were 97 and 3%, respectively. In addition, the risk ratio and allelic reliability were obtained for T allele was OR: 3.06: and CI = 0.31 – 29.94 and for C allele was OR: 0.32: and CI: 0.03 - 3.19, respectively. Finally, statistical analysis showed that no significant difference was observed between the two groups (P > 0.05). Conclusions: The results of the present study showed that rs13393577 polymorphism in the EGFR gene (ERBB4) is not a genetic predisposing factor for breast cancer.
